Section 6: DLSw+ (4 Points)

Configure DLSw+ between VLAN2 and VLAN4; use routers R8 and R5. Peer
from Lo0 on R8 and the VLAN4 interface on R5; ensure that R8 can accept DLSw+
connections from only unknown TCP peers.

Peer as requested from Lo0 on R8 and configure this peer as promiscuous with
TCP for the future connections. Configure R5 as requested and configure your
bridging parameters to ensure the required connectivity. You should be concerned
about this question; it is too easy and this should be ringing alarm bells. If
you have configured this correctly as in Example 1-53 and Example 1-54, you have
scored 2 points.

Set up a one-line filter, which only allows common SNA traffic to
egress from R5 VLAN4 into the DLSw+ network.

You are required to configure lsap-output-list, which allows only the
SNA common traffic listed under access-list 200 to egress the DLSw+ connection
to R8 on R5. If you have configured this correctly as in Example 1-55, you have
scored 2 points.
